the like. r, Heretofore, operators of or other foreign particles. I usually satisfactory and protected the eyes, they did not protectthe face and other parts of the body of theoperator from inJury,'nor nearby workmen engaged in other duties. Also, it was necessary for the chipping hammer operators to I wear goggles the greater part of the day, and goggles become quite uncomfortable to the wearer after continuous use over such a long period of ime. I

It has been proposed to attach safety guards to chipping hammers and the like, but such thereof, thereby tending to discourage their use entirely, which, of course, defeats the p p se for which they are intended. v I

According to the present invention, there is provided an improved safety guard which is safe and easy to use'and, when once adjusted to position, cannot be easily shifted-therefrom It is an object of the present invention to provide a simple and inexpensive safety guard which I will encourage its use and protect other workmen in the immediate vicinity as well as the operator. It is another object of the invention to provide I a safety guard for use with chipping hammers and the like which will deflectthe chips or other foreign particles downwardly,

.Inb ligure isapi or tne new,

1938, Serial No. 226,548 lo]. 2-11) I safety guard of my invention, showing it attached to the operators arm as in use; I

Figure 2 is an enlarged plan of my inproved safety guard;

Figure 3 is a section taken on the line 5 of Figure 2; and,

Figure. 4 ma plan showing a modified bracket for attachment.

Referring more particularly to the drawing, the improved safety guard of my invention comin prises a deflecting shield 2 consisting of a curved frame 3 preferably made from sheet metal hav;- ing an opening in the center thereof which is covered by a transparent material, preferably a wire mesh screen d, which may be welded, solid dered or otherwise attached to the frame in. any suitable manner, with the mesh of .the wire being small enough to prevent chips or foreign particles from coming therethrough. A 54 inch wire mesh screen has been found to be satisfactory for so most purposes.

There is arranged on the top side of the frame 3 a bracket 5, which may be riveted, welded or secured to the frame in any other suitable manner, having a hole therein which is adapted to 2:; receive a supporting rod 6. The rod 6 is prefera ably curved, as shown in Figures 1 and 2, or it may be straight with the end turned outwardly,

The opposite end of the rod 8 is adiustably po- 35 sitionedEin-an opening of a bracket 8 carried by a relatively wide strap 9, preferably made of leather; which isada'pted to be attached to the for adjusting and holding that end of the rod in the bracket. l

It will be seen that the thumb screw. I in the brac 'etji and the thumb screw if in the bracket 8 will permit suitable adjustment of the rod and shield sideways; also, these screws will permit adjustment of the shield on the end of I the work to be chipped or worked upon.

There is shown a leather strap for attaching the safety guard to the arm of' the wearer but it mu be understood any suitable means of .tttachmentmay be provided, such as a reu more, it will be seen silient bracelet-like metallic strap. It is desirable that preferably a rod or flat member be used to connect the shield to the arm strap as such a member can be easily bent to conform to the angle which the hand may take on the hammer and thereby may be comfortably adjusted -to the arm of any particular operator.

As a result of my invention, it will be seen that I have provided an improved safety guard for the use of workmen operating chipping hammers which will not interfere with the operator or the holding of the hammer, and if the operator desires to inspect the work, it is necessary only to move his hand from the hammer, thereby allowing a clear view of the work.

that accidents to fellow workmen, as well as to the operator, will be greatly diminished by the use of the improved safety guard of my invention.

While I have shown and described one embodiment of my invention, it will be imderstood that this embodiment is merely for the purpose of illustration and description, and that various other forms may be devised within the scope of my invention, as defined in the appended claims.

I claim:

1. A safety guard for the use of workmen operating chipping hammers and the like comprising a frame, a wire mesh screen arranged within said frame for deflecting foreign particles and Furtherenabling the workman to view the work-piece therethrough, a strap member for attachment to the arm of v the workman, an inherently rigid outwardly extending supporting member'extending between said frame and said strap, a bracket member carried by said frame for movably at tachlng one end of said rigid supporting member thereto, a set screw associated with said bracket for holding the end of said rigid supporting member adjustably therein, another similar bracket member carried by said strap member for movably attaching the opposite end of said' rigid supporting member thereto, and a set screw associated with said last mentioned bracket for holding that end of said rigid supporting member adiustably therein.

2. A safety guard for the use of workmen operating chipping hammers and the like comprising a deflecting shield adapted to be positioned over the working tool of the hammer, a

strap for attachment to the arm of the operator, an inherently rigid outwardly extending shield supporting member extending between said deflecting shield and said strap, adjustable means for connecting one end of said rigid member to and adjustable means for connecting rigid member to said said strap, the opposite end of said shield.
